I'm getting slightly poor mileage on my Regina-equipped 740. Just replaced the coolant temp sensor, but I want to go ahead and replace the FPR and the O2 sensor for good measure. IPD only has the Bosch FPRs, and they don't seem to indicate if any of the O2 sensors are Regina-compatible. FPC Groton claims the Bosch O2 sensor works for both, which I don't think is true.
I'd like to avoid going to Volvo for the part, since I don't want to take out a loan. Are there other vehicles that use the same pressure regulator? Autozone only comes up with the Bosch items for a Volvo 740. Thanks for any help.
